SEAL-FASTENING.

Specification of Letters Patent.

Patented April 14, 1908.

Application flled October 8, 1907. Serial No. 396,464.

To all whom it may concern:

Be it known that I, THoMAs E. MURRAY, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented a certain new and useful Im rovementin Seal-Fastenings,

. of which the to lowing .is a specification.

The invention is a seal fastening whereby two loops or eyes may besecured together by means of a-wire and holding block or seal body insuch a way as that the ends of the said wire cannot be withdrawn fromthe holding block after insertion therein.

The object of the invention is to prevent the opening of doors, lids,covers, and the like, and generally the separation of objects whichitmay be desirable to retain connected.

The invention consists in the construction of the wire fastening loophaving its end portions turned backward to form portions ofsubstantially V shape, a recess having two contracted entrancesrespectively receiving said V shaped portions and an enlarged innercavity wherein said V shaped portions are free to expand and becomelocked by abutment of their extremities u on the inner surface of saidrecess: and w iereby the wire is permanently retained in the block, sothat said block cannot be used a second time: also in the combinationsmore particularly set forth in the claims.

I In the accompanying drawings-Figure 1 is a vertical section on theline aca: of Fig. 3.-

Fig. 2 is a transverse section on the line yy of Fig.3, and Fig. 3 is atop view of my improved seal block. Fig.4 is a modified form also insection on line :c-a: of Fig. 3.

Similar numbers of reference indicate like arts.

The holding block or seal body 1 may be made of orcelain or otherfictile material and of cyhndrical shape. It has an internal recess orcavity 2 with two contracted en- Opposite the solid partitionbetweensaid entrances, said recess is pro vided with an inwardprojection 5. The sides 6, 7, of the recess are inclined toward .theprojection 5 and between said sides and the sides of the projection areformed curved seats 8, while between'said sides and the entrances areformed shoulders 9.

The fastening wire 10 is in loo form and has its end portions turnedbacliwardly in substantially V shape. In each standing part of the wireand located between. its loop and the extremities of the turned backportions are crimps 11. In the form shown in Fig. 1, the end portionsare turned backward and inward in V sha e and the crnnps 1] are bentinwardly. In t is form shown in Fig. 4,

the end ortions are turned backward and outward in V shape and thecrimps are bent outwardly. In Fig. 1, 12 and 13 represent the eyes whichare to be retained together by means of the device.

In operation, the turned back portions are presse' closely against thestanding parts of the loop and inserted through the entrances 3, 4,until the a exes of the Vs are seated in the seats 8. Tie extremities ofthe VS on entering the recess spring away from. the standing arts of thewire. shown in ig.- 1, they both come opposite the In the form innercurved surface of the solid material of shaped portions. In both casesthe orimps.

11 are received and fit in the entrances 3, 4. It is impossible towithdraw the wire from the holding block because in the form shown inFig. 1 the extremities of the V shaped portions get an abutment on thesolid material of the block between the entrances, while in Fig: 4equally they get an abutment on the shoulders 9. Nor can each part ofthe wire be withdrawn separately from the block in case the loop wire iscut. possible to replace the fastening to re-use the seal block. I
